Miller Electric Mfg. Co.’s The Spoolmate 100 Series features a recessed contact tip and a clear spool cover to help reduce the number of burnbacks. A burnback is when the wire “burns” back to the contact tip and melts to the tip. This ruins the contact tip. The Spoolmate 100 Series also features dual V-knurled drive rolls to ensure consistent feeding of aluminum, which lacks the column strength to reliably feed through a standard MIG gun. Users can also adjust drive roll tension to match the wire being used. The Spoolmate 100 Series comes standard with a 12-foot gun cable, two feet longer than most competitive spool guns, and comes in a convenient carrying case that also holds extra contact tips, nozzle and wire spool. Miller recently released the Millermatic 140, Millermatic 140 with Auto-Set and Millermatic 180. All incorporate Smooth-Start technology, which initiates the arc in a controlled manner, providing spatter-free starts. The Millermatic 140 with Auto-Set eliminates the guesswork of setting welding parameters; when welding mild steel with C25 gas, the user only has to choose his wire diameter and metal thicknesses and the unit sets the optimal welding parameters.
